Title: Sheet stack-up device
Inventor: NAGASAWA YUTAKA
IPC: B65H29/40
Filed: 1985-04-17
Abstract: PURPOSE:To stably insert a paper sheet which is highly foldable and flexible, between blades, by providing a feed-in means for applying a feed-in force to a banknote with the use of the recovering force of the paper sheet which is generated when the banknote inserted in part between the blades is forcively shifted both directions in an blade wheel along the outer periphery of the blades. CONSTITUTION:When a banknote B having its leading end folded outward or curled, enters through a conveying path 24, belt 26c positioned inward of blades 22 makes into slide contact with the outerward folded or curled section of the banknote B so that such a deformed section is returned to its normal condition and is introduced into the gap between the blades 22. Further the belt 26 forces to shift, inward of the blades 22, the banknote B which are being inserted into the gap between the blades 22, and therefore, the banknote B makes into strong contact with the belt 26c by the recovering force of the banknote B due to forced deformation. The frictional force between the banknote B and the belt 26c during this stage becomes greater than the frictional force obtained between the blades 22 in the vicinity of the leading end of the banknote. As a result, the belt 26c may push the banknote B surely and stably into the gap between the blades 22, overcoming the frictional force obtained between the blades 22 in the vicinity of the leading end of the banknote B.

Title: Device for maintaining braking pressure
Inventor: SUGAWARA HAYATO
IPC: B60T11/28
Filed: 1982-05-14
Abstract: PURPOSE:To simplify the structure of a braking pressure maintaining device comprising a liquid pressure maintaining valve and a check valve and facilitate the processing and assembly of the device, by placing both the valves on the same axis and providing an integrated seat for the valves. CONSTITUTION:When a solenoid 11 is excited, a plunger 12 is attracted rightward so that a poppet 16 which serves as a liquid pressure maintaining valve is brought into pressure contact with a seat 17 through a rod 15. As a result, pressure chambers 19, 20 are disconnected from each other so that a master cylinder and a wheel cylinder are disconnected from each other. In that state, the liquid pressure of the wheel cylinder is kept unchanged even if that of the master cylinder falls. A ball 27, which serves as a check valve, is housed in the seat 17 and urged by a spring 28 in such a direction as to cut off the communication passage between the pressure chambers 21, 20. When the pressure difference between the pressure chambers 21, 20 has become stronger than the force of the spring 28, the ball valve 27 opens to balance the pressure of the wheel cylinder and the master cylinder.

Abstract: PURPOSE:To improve the photoelectric conversion efficiency of a solar cell and the like by growing sequentially an SnO2 film wherein recombination levels of minority carriers are increased and a low-resistance SnO2 film on an Si substrate in an oxidizing ambience containing Sn vapor or the like. CONSTITUTION:On an N type Si substrate or a thin Si film formed on another substrate is formed the SnO2 film in the oxidizing ambience containing Sn vapor or Sn compound vapor, whereby the photoelectric conversion element formed of heterojunction is prepared. As this SnO2 film, two layers thereof having different properties are grown. The first-layer SnO2 film is formed to be 10Angstrom  or more thick at the temperature in the range of 320 deg.C or less and the recombination levels in the film are increased to raise open-circuit voltage Voc. As for the second-layer SnO2 film formed subsequently, the temperature for growing is raised to 340-420 deg.C, while N type impurity is applied to an ambience as occasion calls to make the film be of low resistance, so as for the high terminal voltage of 0.8 to be obtained at the time of outputting. By this constitution, the conversion efficiency can be improved and thus the device can be made fitted for the solar cell and the like.

Title: Irradiation with laser
Inventor: YAMAZAKI GENICHI
IPC: H01L21/268
Filed: 1989-03-30
Abstract: PURPOSE:To easily and automatically execute an accurate alignment operation between a laser beam and a pattern by installing the pattern on a specimen which is irradiated with a laser, a mark whose center of gravity is identical to that of the pattern and which is used exclusively for position detection. CONSTITUTION:If a pattern on a specimen and a mark for position detection are shown typically, Si islands 1A surrounded by an insulator, e.g. SiO2, and marks 2A, 2B for position detection are formed on the insulator. Since the center line of rows of the Si islands 1A in an X-direction coincides with that of the marks 2A, 2B for position detection in this case, it is sufficient that the patterns are irradiated with a laser by paying attention to only the marks for position detection irrespective of shapes of the patterns on a silicon wafer 3, which is very efficient. Thereby, even when the whole surface of the specimen is irradiated with the laser, it is possible to obtain a laser irradiation method in which a laser beam, is not displaced from the patterns.

Abstract: PURPOSE:To make the said pressing force maintainable in a proper manner at the time, by securing the pressure force of a vane against the inner wall of a cylinder with such centrifugal force as acting on the vane and lubricating oil pressure in time of low-speed operation, while in time of high-speed operation, making full use of the centrifugal force, through the lubricating oil force is reduced to some extent. CONSTITUTION:At an oil feed passage for giving pressing force to a vane 7, there are provided with a ball valve tappet 27 receiving an action of centrifugal force by operation of a compressor, an oil feed port 26 of a lubricating oil passage 22 in front and in the rear of the ball valve tappet 27, a slide chamber oil feed port 29 installed in a valve seat 28 and a spring 25 which presses the ball valve tappet 27 to the oil feed port 26 in time of stoppage. With this formation, the pressing force against the inner wall of a cylinder 1 of the vane 7 is secured through such centrifugal force as acting on the vane 7 and lubricating oil pressure in time of low-speed operation, while in time of high-speed operation, lubricating oil flowing into a vane slot is intercepted, reducing the forward pressing force produced by the pressure of lubricating oil, and on the other hand, the growing centrifugal force of the vane 7 is increased instead, thus the pressing force is always properly kept up. As a result, wear in the inner wall of the cylinder 1 can be reduced and a significant improvement in durability is made possible.

Title: Feature extraction method for printing matter
Inventor: KITANO KIYOSHI
IPC: G06T5/00
Filed: 1995-03-02
Abstract: PURPOSE: To increase the difference of density between an extracting object and its background and to attain the separation between them with high precision by increasing the density of the extracting object compared with its background density through the conversion of density and then performing the γ conversion and the density gradation conversion. CONSTITUTION: The print pattern read by an image sensor camera 3 is inputted in an image. The look-up table conversion such as inversion, etc., is carried out as the pre-processing so that the density of an extracting object included in a printed matter 7 is increased compared with its background density. Then the γ conversion is given to the image that undergone the pre-processing to increase the difference of density between the extracting object and its background. Then the density gradation conversion is performed after the 7 conversion by means of a look-up table consisting of 3 straight lines. As a result, the density of the extracting object included in a high density area is kept as it is. The image that undergone the γ conversion is binarized by a certain threshold value of density and the extracting object is separated from its background. When the background noises discontinuous to the extracted binary image are detected, the image processing such as labeling, etc., is carried out to eliminate these noises.
